Okay, that settles it.
I knew I wanted my new story to be set in a tiny town somewhere in Pennsylvania (why PA?
I don't know. My imagination sometimes makes these decisions without bothering to inform the rest of me). Problem: I don't know from PA. I've been to Pittsburgh once, for less than 48 hours.
So I go surfing, trying to pick a location. I stumble across Butler County, which I recognize as the annual location of Pennsic. But I've never been to Pennsic (camping with 10K strangers pushes all my phobia buttons), so I am hesitant to explore it further.
THEN! I discover that Night of the Living Dead was shot there. That decided it for me. If a county is willing to host the original zombie invasion, that's good enough for me!
